6 Claims.

This invention relates to building constructions and devices, and has reference more particularly to building constructions in which joint reenforcing material is movably attached to plaster or 5 other building boards.

In the construction of walls, it is common to nail plaster boards, fiber boards, or other building boards to wooden studsor joists, or to secure said boards to steel framework by means of clips.

to receive the plaster surface coat; also toim-- prove building constructions in other respects hereinafter specified and claimed.

Reference is to be had tothe accompanying Fig. 1 is a sectional elevation of a wall constructed in the improved manner. with parts broken away to disclose theconstruction,

Fig. 2 is an elevation 'of one of the clips for attaching the reenforclng element to the boards prior to shipment, and

Fig. 3 is a sectional view on a large scale through the edge of a board showing the reenforcing element in shipping position.

Referring to the drawing by numerals, studs 10 and joists ll form the framework of a room or building. Boards l2 are attached to. the frame members It and II by means of nails it with their edges ih abutting relation, The boards i2 may consist of a plaster core ll having paper cover sheets l5, or said boards may consist of vegetable fibers or other desired. material.- To one or more edges of each board II, a reenforcing element I6 is loosely attached, said element consisting of astrip of expanded metal,'wire mesh or other suitable material. The reenforcing element It is movably and slidably attached to the board edge by means of a spring wire clip l1- having a detent itatthe outer end which presses against the 'reenforcingelement i6 and holds it in shipping position with the outer edge the. element preferably positioned somewhat inside the edge of the board. 'rneinner end-o! clipl1isbentlaterallytoformatransyersely drawing forming a part of this specification, inwhich i extending section I9 which in turn is bent to form a section 20 which extends longitudinally ,of the clip H. The section 20 is return bent to form a section 2| which terminates in outwardly extending pointed prong 22, the latter being forced through theboard l2 prior to shipment. The end 23 ofjprong 22 is bent or clinched laterally against the back of board I! so as to firmly seat the section l9 against the front face of the board, said section I 9 serving to stabilize the clip I! and prevent-any tendency to tip. At the time of shipment and during erection of the boards, the re enforcing strip, It will be held in from the'edge of the board by clip as shown at the left hand of Fig. 1. The workman. then moves the strip l6 toextend'over the board joint as seen at the right hand of Fig. 1. A coating of plaster 24 is then applied over the exposed faces of the boards l2 and strips ii in the usual manner. After the plaster has set and dried, a decorative coating 20 of plastic paintgwallpaper, etc., is applied to theexposed face of the plaster. I- would state in conclusion that while. the illustrated example constitutes a practical embodiment of my invention, I do not wish to limit myself precisely to these details, since manifestly the same-may be considerably varied without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new. and desire tosecure by, Letters Patent:--

1. An .article of manufacture comprising a building board, a strip of expanded metal reenforcement slidably positioned, along an edge of said boardandmeans for removably securing said strip to a face of said board. 2.;An article of manufacture comprising a building board, astrip.of reenforcing material slidably positioned along an edge of said board,

and a spring clip attached tosaid board and adapted to removably secure'said strip to a face of said board.

' 3. An article" of -man'ufacture comprising a' building board, a strip of expanded metal joint reenforcement slidably positioned along an edge of said board, a spring wire clip having a prong adiacent'one end and extending through said board, the end of said prong. being clinchedagainst one face of said board, and a detent formed on the opposite end of said clip and adaptedto bear against said strip and removably se care said strip to a face ofsaid board. 4. An article as described-in claim 3 characterized by a flat section on said clip adapted to bear against the face of said board so as to stabilize saidclip to prevent-tipping thereof.

I 5. In a building construction, a stud, a pair of boards secured to said stud with edgesabutting,

6. A spring wire clip suitable for the slidable attachment of reenforcing strip to a building board, comprising a wire clip body,-an outstanding prong formed between the ends of said body,

and a detent adjacent one end o1' said body for 5 yieldingly engaging said strip. I a
